Description
The FNP300 Series provides highly-efficient ac-dc power supplies, each with one high current output and an
additional standby output, which can be used in a wide range of applications. Passive current share along with
internal ORing diodes allow the FNP300's to be also used in redundant, hot-swap applications. All models meet
international safety standards and display the CE Mark for the low Voltage Directive.

** (1) Standard FNP300 models (without "H" at the end of part number) have latching inhibit function, i.e., once PSU is
inhibited, it needs input power re-cycle to allow using enable state again.
(2) FNP300 variants marked with "H" character do have non-latching inhibit function so there's no need to
re-cycle input power when enabling unit after inhibit state.
